使用OLE在Delphi中检索Outlook“收件箱”和“已发送”文件夹

Question

What's the best way to go about extracting Outlook folders from within Delphi? Ideally I'd like to retrieve the Inbox folder and any other folders within it. I don't require the email headers/message just purely the folder names.

Delphi BDS 2006

See here for Outlook's Object Model. Below displays the names of folders in the Inbox:

procedure TForm1.Button1Click(Sender: TObject);
var
  Outlook, oNameSpace, Inbox: OleVariant;
  i: Integer;
begin
  try
    Outlook := GetActiveOleObject('Outlook.Application');
  except
    Outlook := CreateOleObject('Outlook.Application');
  end;
  oNameSpace := Outlook.GetNamespace('MAPI');
  oNameSpace.Logon('', '', False, False);   // not sure if this is necessary
  Inbox := oNameSpace.GetDefaultFolder(olFolderInbox);
  for i := 1 to Inbox.Folders.Count do
    ShowMessage(Inbox.Folders[i].Name);
end;
